Much of this problem space I've solved with running MTR to the destination when troubleshooting to see each hop's detail.

It's like ping + traceroute in a live running session with each hop broken down.

Quite consistent when I am the first to notice a node down on Xfinity network and in the same mtr see my network at least to my modem is good. Or when there's a hop beyond my ISP with 100s of ms added latency, which I haven't seen other tools do well like MTR can.

Won't solve everything, but might be worth your checking in your case as it breaks down per-hop providing latency for each.
